Hello,
This series adds CPU frequency scaling support for the TI AM62L3 SoC.
The AM62L3 is a low-power, low-cost SoC from Texas Instruments. This
series enables cpufreq support by:
1. Adding the SoC to the cpufreq-dt-platdev blocklist to prevent the generic driver from probing.
2. Extending the ti-cpufreq driver to support AM62L3 speed grading by reading the efuse.
3. Updating the device tree with the necessary operating points and clock configurations.
Tested on AM62L3 EVM [1]

From what I spoke with Nishanth yesterday, the DT patch (3/3) will have to go via his tree as it's ti-k3. The first 2 patches are the cpufreq subsystem ones, once you apply those and they are integrated Nishanth can pick up the DT patch. -- Best regards, Dhruva Gole Texas Instruments Incorporated
